That has to be the reason Kristen Stewart's temper heated up while a paparazzo videotaped her as she left a building.
And when we say heated up we mean boiled over in a damn foul way!
KStew dropped a few four-letter bombs as she slammed the paparazzo who appears to have kept his distance, but did pry a bit too much by asking a couple R-Patz questions.
He might not have gotten an answer about her love life, but he did capture her in all her vulgar glory!
But we wish she would've covered her innocent pup's ears before spouting off the nasty rant!
